OK, What makes you think a bad valve to justify head removal in the first place John? I would bring into serious question how only 1 valve could fail. Now I COULD EASILY beleive a lifter failed or collapsed, bent pushrod, broken rocker or stud, etc. NONE of which requires head removal. At worst, maybe timing set or at absolute worst, cracked head. That is another matter.
Second, assuming all else is good, sounds like a good plan. Yer motor is VERY resilient to stupid $hit, beleive it or not, so why only one BAD valve?
That would be the line of questionong I would start with John.
